"We actually got all the way down here from Devonport yesterday on a single charge, which is something that was just unheard of even three or four years ago," he said.

But Brogan's tour hit a snag when he discovered he could not repower the car at a Hobart charging station fast enough to make the ferry back to Melbourne.

He said the lack of charging facilities in Tasmania could become a problem once electric vehicles became more widespread.

"Not everyone's driving an electric car but as they do start to become more popular and cheaper, which is something that will happen over the next 18 months to two years, we're going to start finding ourselves a little bit short on charging stations," he said.

Brogan said there was an increasing number of electric vehicle charging stations in Sydney and Melbourne and, to a lesser extent, in Brisbane and Perth.

Labor sees opportunity for Tasmania

The Opposition used the failed tour to spruik its policy of public investment in electric transport.

Shadow treasurer Scott Bacon said the Government should invest more in supporting electric cars.

"We need to make sure we have the correct infrastructure around the state," he said.

"We think that there will be a market.

"We know that public transport here in Tasmania is largely buses.

"We want to see that looked at - converting those to electricity in the future so that we can use our renewable energy advantage."

Brogan's car was transported by truck to Launceston on Wednesday afternoon ahead of a trip back to Melbourne on board the Spirit of Tasmania ferry

Car can be recharged using ordinary power points: Tesla

The company that built the Tesla Model S driven by Brogan pointed out it was possible to charge the car from any regular power socket.

"Matt, if he had had the time, could have plugged into a normal power point," Heath Walker, the company's marketing and communications manager, said.

"We're also putting in super charger networks [between Melbourne and Sydney] which charge the car half-full in 20 minutes."

Mr Walker estimated that, in the absence of a "super charger", Brogan would have needed to charge the car overnight to be able to make the whole trip back from Hobart to Devonport.

"The car actually tells you how much charge you will have," he said.

"If you decide to ignore it, I'd suggest it's very much on the driver's onus."

Mr Walker said there were roughly 75,000 Tesla electric cars on the road worldwide.
